Sequential Async Queue
Example
function runSequential(items) {
let chain = $.Deferred().resolve().promise();
items.forEach(function(item) {
chain = chain.then(function() {
return processItem(item);
});
});
return chain;
}
runSequential([1, 2, 3])
.done(() => console.log("All done in order")); Pro Tip
Starting the chain with a pre-resolved Deferred is a clean pattern for sequential queues.
